GOOG's earnings will be released 7/21. This is right before the expiration date.
I entered into this today with a Call Credit Spread .
Sold ten, 460c, and bought ten, 470c. (Potential profit of $1250 if it does not go above 460 @ exp). I usually bail out of the short side the day before expiration if the price is within $10 of the Long strike. Has worked good for the past 3 consecutive months.

I did some quick math and your potential profit seems a bit off... but maybe I'm calculating wrong... care to elaborate?
